Bug Fix

Text icon for <...> is <...>spamming in console if any usage of disguise text icon is invoked
Full Changelog: https://github.com/NiFeather/FeatherMorph/compare/2.8.0-alpha.1...2.8.0-alpha.2
New Features
- Now an instance of
DisguisePropertycan declare that it's invisible for the client mod- FeatherMorph doesn't have properties that require this feature yet; it's mainly made for other plugins' development.
- Added
readStringmethod forInputHandles. - The plugin will now attempt to show the exception's message if it occurred while updating or has been forwarded to the
DisguiseState. - Bring the ability for async player data loading in Instance Network to
IManagePlayerData.- Currently, only when the Instance Network is enabled, and the current server is a Slave Server in the network, the async loading feature is fully utilized.
- If supported, when a player enters the configuration state, the plugin will attempt to load their data async, and wait for up to 150ms per player, then allow them to keep logging in after the timeout, and notify their client when the data finishes loading.
- We wait for up to 150ms is to make sure that the disguise unlock data can immediately be available after the player logs in on fast machines.
- And maybe this waiting feature would be removed in the next (edit: next or future) releases, as it literally conflicts with the async concept... 🤯
Other
- Simplified exception handling in some places.
- The message
morph.error_while_disguising_user_faultin the language file has been renamed tomorph.error_parsing_property. - The interval of batching player data requests has been changed from 10 ticks to 2 ticks, to adapt to the new
IManagePlayerData#loadPlayerDataAsyncmethod

This is a release on the 1.21.11/feature branch.
New Feature
- [2.7.0] Added new debug command
/debugForValue, for listing all registeredSingleValuein the given value set. - Added support for Zombie Nautilus's variant property.
Other
- [2.7.0] We are now 1.21.11
- [2.7.0] Bumped PacketEvents to 2.11.0
- [2.7.0] Added a workaround not to send the packet if we have a huge data body.
- This prevents exceptions from being thrown when trying to send a huge amount of available disguise or a huge disguise data.
- Currently, I have no idea how to solve the problem, so let's not sync the list for now. Players can still select the disguise using the
/morphcommand, and other features would still work... Unless the data still exceeds the limit.

/fm extract language <lang>command- Permission for this command is
feathermorph.admin. - If there's already a matching file on the disk, the extracted file will install to
messages/<lang>.fmnew.jsonby default - You can overwrite it by using
/fm extract language <lang> true, this operation requires you to confirm by executing again
- Permission for this command is
- Slaves in the Instance Network now request data for the player when they join, instead of the master server loading and syncing all data to slaves upon startup.
- It's now possible to get the relevant
DisguiseStateinstance inPlayerUnMorphEvent. - Third-party plugins are now able to add their
SinglePropertyinstances toDisguisePropertieson bootstrap, which would allow automatic assignment from player inputs.

by_sightmirror mode now respects the maximum affect distance set in the config- Gradle task
runFoliais now available - The actionbar message for disguise is now handled by
DisguiseState. readRotationsfrom InputHandles now throws an error when the player gives more than 3 elements- This means that giving more than 3 elements for various rotation properties for the Armor Stand disguise will now result in an error message.

ConfigOptionenum toConfigOptionclass from PluginBase

feathermorph.disguise_properties.use - Added permission for setting a custom skin profile for items in
entity/equipmentproperty, restricted to ops by default:feathermorph.disguise_properties.custom_skin_on_items - Added support for Mannequin disguise
- Mannequin disguise is not collectable using the Magic Bottle by default

- Added Weather State property for Copper Golem disguise
- Initial compatibility(?) for Ping Wheel
- Using the official Ping Wheel plugin will work, but pinging while disguising doesn't mask the pinger
- ...So I made a custom plugin to temporarily solve the problem, which can be found at https://github.com/MATRIX-feather/pingwheel-plugin-forked
- Initial support for players with permission
feathermorph.mirror.mannequinto mirror their sneaking actions to mannequins that have the same name and description as their disguise- For BY_NAME executor, mannequins within a range are selected, while setting the affect distance to -1 would disable the range limit

feathermorph.disguise_use_real_uuidpermission is given- Players got removed from their TAB view when undisguising
- Disguise not presenting when teleported from far away, or switching gamemode from spectator
slime_magma/sizeproperty has a wrong random range- Nobody is calling
BaseLivingEntityProperties#setupPropertiesFromEntityin the override methods- This makes disguises that have extra properties not copy the target entity's custom name.
Other
- We are planning to remove the BY_RANGE mirror executor in the future, as it's causing chaos when we have players with bad networking
- Some exceptions thrown will now be forwarded to DisguiseState and will undisguise the player
- Tweaked how Server Renderer rebuilds entity metadata packets sent from the server

This release may require some manual operations
Disguise Tool and Magic Bottle's recipe is now registered using a datapack. While this can allow you to customize even more, you would need to install a recipe management plugin if you wish to disable one of them specifically.
If you have already disabled recipes using a management plugin, then no operations would be required. (As the datapack is using the same recipe ID as the old behavior)
You might also want to read the 2.4.1 changelog if you are updating from older versions.
New Features
- The collected result for the empty Magic Bottle is now a loot table
- By default, the plugin will process all output items that come from the loot table
- You can set custom data
feathermorph:skip_magic_bottle_setuptotrueto make the plugin skip a specific item - For more details, see the Loot table datapack
- Due to a limitation, not all loot table types are supported. Currently,
emptyandentityare tested to work well
- Added permission
feathermorph.acquire_morphto control whether a specific player can unlock disguises via gameplay - Added permission
feathermorph.disguise_use_real_uuidto control whether a disguise should use the player's real UUID for the virtual entity- This may help to improve compatibility with Simple Voice Chat, etc.
- However, this should be tricked as a hack or workaround
- Players are now able to discard their unlocked disguises using the
/discard-morphcommand
Bug Fixes
- Cat and Wolf disguises don't have collar color property applied if targeting a valid entity
/fm make_disguise_toolcommand not registering- AI Modification failed to inject and caused a log spam for some setup
Other
- AI Modification is now disabled by default for new installations
- We now use NMS to inject goals again, as using the API is causing issues...

- Some mobs don't panic from players where they should
- Cats and Ocelots are missing an attack goal for players' disguise
- Tamed mobs still run the custom attack goal
Other
- Removed debug output ("ToAvoid is xxxxx") spamming in
MorphBasicAvoidPlayerGoal - Ensure that the target entity is on the same thread as the running mob in
MorphBasicAvoidPlayerGoal- Nobody reported relevant issues before, but just in case :D
